Forest Hills, in the county of Queens anti apparent in the constructionjuet (loom-.1

i This invention relates to improvements in looomo'tives anal its natureand objects ant: advantages will he, perilous best 'UDClQISiZOOii from ebrief statement oi present practice.

In the constmiction, :zln'ioet universally useli with locomotiiieehaving the lire hos placed; back of the driving Wheels and ham-- mg atrailer truck, the main frame extends through from the lost th'ivi'ogWheels to the hack cool of the locomotive. The frame usually consists oftwo Hat slabs of forged steel, or {L steel casting in which foot pleteeencl boiler supports, both front and rear are cast together with. thesitle members. The trailer truck, usually of the two-Wheel type, ispivotelly connected to the main frame just back of the rear drivers :mcli-ecl'etes uncli-zi'neeth the res].- extcnsion oi the frame or framecradle, the sizperimposecl Weight being transmitted to the truck throughmeans oit'slicling plates, rockers, or swing links. In this constructiontmctive force exerted by the locomotive eng'ne is carried through theframe anti toot plotsettoched thereto, end transmitteii to the tenderWhch follows the locon'iotive 'io z moons of a drewben it will he notedthat in this construction the frame structure the locomotive carries allat the trective effort exertetl. by the locomotive engine anti thetrailing truck is purely e cei'rying ttucit. By reason of the mpitlincrease in size of locomotives and the Weight tltiereoi, oertilll'lwell-defined limitations have hccome hell, and these limitations presenta serious handicap upon iurtlicr development of the locomotive es :1whole, as Well as presenting d'l'llcultics in the iiesign aucl operationof present types of locomotives. f .A.1nongtl1ese (liliicnlties thefollowing may be noted: The connectionlromthe locomotive to the tenderis necessarily at the ere tremor end of the frame extension nhovementioned and it is eviclei'it that on curves the extreme back end ofthe engine on count of its overhang, has :1 very large littoral motionrelative to the center line of the track, necessitating epeeiiilconstruction of buffers and (lino/hers between the engine anti thetender to allow for the excessive svine; at, the back of the engine. Theswing often amounts to es inuco 12 03:14" each side of the center lineout the truck and it is et once upperent that there one tlilliciiitiesencountei'ecl when it is necessary to provide and moin'tetin o ceupiingbetween engine and tenuiei' suitable for transmitting the very heavylocomotive tiective power now used through a connection which is capableof a side motion greet this.

it will oiso lJG noted that it is untlesii'able to transmit the heavytrective power (leveloped by the ioconiotive eng ne throu connection atthe heel; of the engine w may have, at times.,es.much as 12" or 14"offset from the center line of the track.

Again the size of the locomotives has igi'own to such e point that thetrailer Wheel ecis eie excessive, and one oi the greatest dificulticethe locomotive designer" encounters'is to keep these trailer truck,Weighte Within reasonable l'niits, this being particularly true sincethe iiiu'i'oiiuctiou the locomotive lJOOSiEl" as an adjunct to the mainloco motive engine, such hooste? being ceii'iecl on the trailer truckframe. 7

In addition the ery construction otthc ironic itself and the necess'tyof providing rear frame extensions heavy enough to carry the tracti'veforce of the locomotive and the provision of it truck suliicientstrength to carry the load, reduces the space available fol the ash penunder the box. 'lil'ifi capacity of the ush poo and the size of theopeningthrough the ash. pan. for the atlmiseion 01%; oil" beneath thegrate are important n-nil vital elements in the ope ition oi? thelocomotive boileix end the iimi'tiiltion imposeii by the element abovementioned con stitute o serious handicap and limit upon furtheretlvencein locomotive design and upon, proper opei iit on of many Qlfthc'locomotives as at present cmisti'ucteti.

The introduction. of the hiconiotive booster hate zidtleil fut'thei?problems in that the booster must else he accommodated in the liinitetisplice et the heck end of the -locomotive undecneeth the lite lion; and'lltll'le extensions we at present iilcsigz'ietl 'ltis high to securetill}? his purpose and thus the size of such an auxiliary power unit islimited.

In such locomotives as are equipped with Stoker mechanism, it will beseen that the conditions above noted are rendered still more marked.

It is one of the primary objects of my invention to provide an improvedform of locomotive of simple construction which meets the dillicultiesabove mentioned; and in which, also, a maximum space is made availableunderneath the fire box for the ash pan, the booster motor, stokingmechanism and other parts.

Another object of my invention is to provide an improved form ofarticulated frame construction in which the frame portions, in edect,operate as a unitary structure, vertically considered, while there isfreedom for swinging or lateral movement of that portion of the framewhich is beneath the fire box. tages will appear hereinafter in thedescrip tion of the invention.

I accomplish the foregoing, together with such other objects andadvantages as may be incident to my invention by means of a constructionwhich I have illustrated in pre ferred form in the aocompanayingdrawings, wherein:

Fig. 1 is a fragmentary side elevation of the rear portion of alocomotive illustrating the application of my improvements thereto; Fig.2 is an end elevation of Fig. 1; Pi 8 is a section taken on the line 33of Fig. 1; Fig. i is a plan view of Fig. 1 with the tire box and boilerremoved; and Fig. 5 is a diagrammatic view illustrating a modificationof my invention. 4

Referring now to Fig. 1, it will be seen that I have shown only aportion of the boiler 7 and the fire box 8, both being of standardconstruction. The frame, however, is of divided construction andcomprises a main portion A extending from a point approximately beneaththe front end of the fire box forwardly underneath the boiler, and asupplemental frame B, the forward end .of which is articulated with therear end of the main frame, as by means of the pivotal or hinge pinconnection-9 which permits the supplemental "frame to swing laterallywith respect to the main frame during curving. I

The main frame may be of standard con struction comprising two sideplates 10, connected together at front and rear by means of the crossties 11. This frame has pedestals 19 to receive the boxes (not shown)for the drivers 13.

The articulated supplemental frame 1B comprises the side members 1.4:,the forward cross member and the foot plate 16 at the rear, all of theparts being preferably made More specific objects and. advanwidth can beemployed.

plemental frame have pedestals 17 for the journal boxes (not shown) inwhich the pair of axles 18, with which the frame is preferably provided,are journalcd. 'lhc supplementabframe is outside the plane of itswheels, and. the side members are in the plane of the axle journals. Thefoot plate 16 is provided with a drawbar pocket 19 which, it will be.seen on inspection of Fig. l, is located at the upper, rear end of theframe; and it is also pro vided at its lower rear portion with aremovable cradle-like cross member 20, serving as a support for thebooster motor, indicated as a whole by the reference letter C. Thebooster motor. if used, is also in part supported on suitable hearingson the rear axle of the supplemental frame in a manner well understoodin this art, and extends rearwardly "from such axle and through thespace between the cradle 20 and the foot plate. It will be noted thatthe construction in so far as thus described, is one by virtue of whichmaximum clearance spaces are made available. both trai'xsversely andlongitudinally of the supplemental frame, i. e., of the lire box.Transversely considercd, the distance between the side members 14 of thearticulated frame may be much greater than would be the case if the mainframe 10 were carried through to the back end of the locomotive as isthe customary practice, and thus an ash pan of maximum Longitudinallyconsidered. the pair of axles 18 of the supplemental frame can be widelyspaced apart, irrespective of whether a booster is used or not, and thusmaximum clearance between the axles is made possible tor'tbe ash pan. liin'ther ash pan ciea rance may be made possible by having one pair ofthe. wheels supporting the supydemental frame of smaller diameter thanthe other, as shown in Fig. if a booster is applied. it is preferableto, make the leading wheels smaller in diameter "than the rear wheels ofthe supplemental frame.

The main frame A is connected to the boiler, in front and rear, in theusual manner, an ex ansion bearer 21 being shown at the rear, )etwecnthe mud ring 22 of the fire box and the cross tie ll of the mainframe-the imposed weight is transmitted through the usual springs 23 andspring bangers 2 The imposed weight may be transmitted to thearticulated frame in any desired man.- ner, but I prefer the arrangementshown, in which I provide fulcrunis 24- on the cross tie at the rear oithe main frame A for the equalizing beams 25 connected by hangers 26 tothe forward end of the springs 27, the other ends of said springs being!wonnected by the hangers 28 to an end of the beams 29 illt) integral.The side members 14 of the sup-fulcrumed on the side members 14: of thesupplemental frame. The rearward encls of the beams 29 are connected byhangers 30 to the forward enil of the springs 31.

In order to provide suiteblc support for the cab (lock, cob Stokermechanism anrl other parts at the back one of the locoiiiotire(heretofore carried. on the rear erten sioroc of the frame), I provide asupporting meaiispreferably carried on the mud of the fire box. In theembodiment shown, this supporting means comprises a pair of members l)which extend along the cities of the rout-l ring 252 for a subst: i-bielolistc ice with their reef curls projecting; beyond the back ii a pluraly of points to extension 252" of the mutl ring by the bolts or rivets35.. The members D Wherethey extcncl along the mucl ring, here oncowardly: projecting, inclined Henge as at their bottom, serving asupport for the ashpah 37' cool they are also provided with an outwardlyattend ing, curved. fiaiigerl portion 38 which lends strength andrigidity and makes it possible to provide openings 39 in the verticalpoof tion 40 of such members of a size such as will admit sullicient airinto the lIOK for proper coii'ibustiosm Those portions of tie mein c'bee and. of thefire box are of channel chaps and. are connected. bymeans of the cross tie or angle ll, curl serve as a support for the cabdeck l2 and ash (l3. The bearer mombere 32 previously mentioned, mayform a part of a cross member 32 and are riveted to the respectivemembers D. The worm ber 32 constitutes a support forrthe SiZOktZI"mechanism diagrammatically imiicatecl at all in Fig, l. Thus ell of thepartp of the locomotive which are connected. to and go with the boilerand lire box are supported by the members l) and are thereby kept infixed relation to the back encl. of the boiler.

The rear or tail portiooof the main fraine provided with tongue-likeprojections e5,

preferably two in number, such projections being; adopted to extend intorecesses #16 formed in the cross tie 15 of the supplemental frame. Therecesses 46 have greater Width than the projections 45 so that thesupplei'ociital frame will have fiectlooifor radial movement about thepin Q as center, but the projections 45 are adapted to seat on thebottom or seat portions i l of the re ii of the box, They are sccoreol'at .rs D extending rearwariily of the pain frame, Wheels supporting thefrom cesses 4.6 and they thus perform two fume? tions; namely, theyassist and cooperate with" the HlEIDbEI'S in maintaining thesupplemental frame in horizontal. alignment with the main freme (it e,as against vertical dis? Tl! placement) and they -servc to transmit,Weight from the main frame to the supple-A mental frame in such cases asWhere the; main drivers pass over a 10W portion in the]: rails, such asat a joint. Thus, vertically '15 considered, the two frames act as aunitary structure with freedom, however, of the sup- H plcmeiital frameto swing laterally with re--. H spect to the meio framecluringcurving";-

Cllhis is of great practical utility because the.

equaliser Work of the main frame'is coupled; .1 to the equalizer Work ofthe supplemental i frame aid the functioning ofthe equalizing: 1 meansconsidered as 21 whole would be materiolly impaired if the two frameswere not in effect unitary, vertically considered. The j horns orprojections l5 also prevent the front cool of the supplemental framefrom kicking up.
